Re: [igraph] version doubt

[Gábor Csárdi]

I am sorry, there was some confusion on my side. I thought you are
using the R version, and not the C version.

First of all, if you are using the C library, then version 0.6 is not
binary compatible, but most code works without problems. You might get
a few error messages in compilation time, because some of the API has
changed, but then it does not take long to check the new documentation
and updated your code.

So you don't need to install both libraries, just remove the debian
package for version 0.5.x, and install version 0.6 by hand, i.e.
download the source code from http://igraph.sf.net, run

./configure
make
make install

This installs igraph into /usr/local/*.

Sorry again for the confusion!
Best,
Gabor
